The upper ends of the upper sections and 11 of the side housings are similarly attached together by the other spacing member 15 also provided with tongues 18 on opposite ends to engage grooves 17 corresponding to those formedin the lower section. i This upper spacing member 15 is also attached to the inside vertical walls of the side housings 10 and 11 adjacent the extreme upper end thereof.

The contiguousor intermediate ends of the upper and lower sections of the side housings are adapted to be secured together by means of the bolts 14 spaced as shown in Figs. 1 and 3. In these ends of the side housings are recesses 20 and 21 forming hal f bearings for the ends of the spindle 22 carrying the work rotating drum 12. Preferably, and as shown in the drawings, the bearings in the opposite side housings 10 and 11 are formed equally within the lower and the upper sections of the side housings so that by removing the upper sections 10 and 11", the spacing member 15 and attached parts, the drum 12 and its spindle 22 may be readily removed.

To rotate the work rotating drum- 12 and the cutter spindles 13 I. motor 25 is mounted on the upper spacing member 15. Driving connections 26 from the motor 25 are provided preferably within the upper end of one of the side housings 11. By means of these driving connections a shaft 27 is rotated on which is mounted a worm 28 which engages and rotates a worm wheel 29. This worm Wheel 29 is on ashort shaft 30 also carrying a worm 31 which engages a large worm wheel 32 on the end of the work-rotating spindle 22. By means of these connections the work spind1e'22 and its drum 12 are very slowly' rotated.

The eutter' spindles 13, rotatably mounted within their heads 13, are provided with worm wheels 35-on their outer ends. These worm wheels 35 are engaged by worms 36 splined or otherwise mounted on vertical driving shafts 37 The upper ends of these shafts 37 are provided with bevel gears 38 in mesh with corresponding bevel gears 39 on a transverse. driving shaft 40 suitably mounted within thev upper ends of the side housings 10 and 11 and the upper spacing member 15. On this transverse shaft 10 is a gear 41 adapted to be drivingly connected to i a gear on'one of the shafts of the driving connections 26. By these means the cutter spindles 13 are simultaneously'rotated at similar speeds.

What I claim is: 1. A milling machine comprising in combination, a pair of opposed side housings adapted to rest directly upon suitable foundations, a work rotating drumsupported thereon between said housings, cutter spindles rotatabl spacing mem ers attached to said housings upon inside .vertical surfaces of said hou s-' ings adjacent the upper and lower ends there'- -of,.and tongue and groove connections between said spaclng members and side housings. "2. A milling machine comprising in combination, a pair of opposed side housings ex-' tending from the floor line to the full height mounted on said. housings,

of the machine. and adapted to rest directly LYNDON c; COLE.
